У меня есть несколько компонентов.
Мне нужно выделять активную строку, по которой был щелчок мыши. Сложность в том, что одновременно может быть выделен только один элемент
<template>
<div >
<div class = "main-window">
<ul >
<Directoire
v-bind:directories="directories"
/>
<span>{{firstWindow[0].dir}}</span>
<BackRowVue
v-if="!(firstWindow[0].dir.length < 4)"
v-bind:whichScreen="whichScreen"
v-bind:firstWindow="firstWindow"
v-bind:secondWindow="secondWindow"
@newvalue="newvalue"
/>
<Item class = "modal"
v-for="elem of firstWindow"
v-bind:key="elem"
v-bind:elem="elem"
v-bind:whichScreen="whichScreen"
v-bind:firstWindow="firstWindow"
v-bind:secondWindow="secondWindow"

<button @click="backToHomeDir(firstWindow[0].dir, whichScreen)"> Back to home </button>

В этом компоненте мы отрисовываем текущую строку и заносим в нее данные
<script>
export default {
props:{
elem:{
type:Object,
default: () => ({}),
},
whichScreen:{
type:Boolean,
// default: false,
},
},
data()
{
return{
delay: 500,
clicks: 0,
timer: null,
activeClass:"",
obj: this.elem
}
},
methods:{
clickOnRow: function(elem, whichScreen){
this.clicks++
if(this.clicks === 1) {
var self = this
this.timer = setTimeout(function() {
console.log("одинарный");
self.clicks = 0
}, this.delay);
elem['buttonON'] = true; // нужно ?
// makeActive();
console.log(elem.buttonON);
elem["whichScreen"] = whichScreen;
this.$emit("selectelem", elem)
} else{
clearTimeout(this.timer);
console.log("двойной");
elem['whichScreen'] = whichScreen;
elem['downOrUp'] = true;
this.clicks = 0;
fetch('/currentDir1',{

makeActive:function(elem){
